PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 355,010. dated December28, 1886.

Application filed May 12, 1886.

Serial No. 201,956. (No model.)

To CLZZ whom it may concern.-

Be it known that I, HARRY M. FARNS- WORTH, a citizen of the UnitedStates, residing at Cleveland, county of Ouyahoga, and

5 State of Ohio, have invented certain new and useful Improvements inPaper Bags, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

1 This invention relates to all classes of paper bags which are providedwith what areknown in the art and to the trade as bellows sides.

The bags of this class, although very extensively used, are to someextent objection- 1 able, because of the difficulty of keeping the mouthof the bag fully open during the operation of filling the bag. Thisdifficulty is caused by the tendency which the bellows folds in thesides of the bag have, whenever go they are opened out, to return totheir original position, and thus draw the sides of the bag together andcontract the mouth.

It is the object of the present invention to overcome this difficulty,and to provide means 2 5 by which the mouth of the bag when once openedwill be maintained in a fully or nearly fully opened position.

To that end the invention consists in providing the month end of the bagwith oblique o creases, which extend from the corners of the mouthinward and downward to the central lines of the bellows sides, therebycausing triangular portions of the material at the ends of the bellowsfolds to bend outward as soon as 3 5 those folds are opened out, andthus hold the mouth of the bag distended.

As a full understanding of the invention can be best imparted by anillustration and a detailed description of a bag embodying the in- 0vention, such description will be given, reference being bad to theaccompanying drawings, in which- Figure 1 is a perspective view of acommon form of bellowssided bag, showingthe same 5 distended and readyto be filled. i Fig. 2 is a top or plan view slightlyin perspective,showing the mouth of the bag. Figs. 3 and 4 are views similar to Figs. 1and 2, showing the same bag provided with theimprovement constitntingthe present invention; and Figs. 5

l and 6 are side views of the bag, illustrating two ways of making thecreases before referred to.

Referring particularly to Figs. 1 and 2, it is to be understood that thebag therein shown is of the form shown and described in Letters PatentNo. 123,811. This form of bellowssided' bag is now so common and is sowell known as to render a detailed description of its constructionunnecessary. It will be ob- 6o served that in these figures, which showthe bag in its opened or distended condition, the bellows folds aproject inward for some distance between the sides b c of the bag, thusnot only contracting the mouth of the .bag lengthwise, but also tendingto draw the sides 19 0 together, and thus contracting the mouthwidthwise. This partial closing of the bagmouth is caused by thetendency which the lines in the paper, to at once spring back intoposition between the sides I) 0 as soon as they are released after beingopened out. This, as before stated, makes it difficult to keep the mouthof the bag fully open during the operation of filling the bag, which isoften a source of annoyance. To overcome this difliculty I provide themonth end of the bag with oblique creases 2, which extend from thecorners of the bag inward and downward to the cen- 8o tral lines of thebellows folds, as shown in Figs. 3 and 4. These creases 2 are so formedthat the triangular portions 4 above them have a tendency to springoutward, as shown, and thereby enlarge the mouth of the bag lengthwise.The portions 4, springing ontward in this manner, also have a tendencyto hold the sides I) c of the bag apart, and thus prevent the mouth ofthe bag from being contracted widthwise. The creases 2 may be formed inany suitablemanner, either by creasing the paper before the bellowsfolds are formed and allowing the portions 4 to remain in the completedbag in the position shown in Fig. 6, or by folding the portions 1outward between the sides of the bellows folds, as shown in Fig. 5.

The particular form of bag shown in the present case has been selectedmerely for the purpose of illustration.

bellows-folds a have, by reason of the creased 7Q The improvement [00constituting the present invention is equally applicable to all classesof bags having bellows sides.

What I claim is 1. A bellows-sided bag having the creased lines 2,extending from the corners inward and downward to the central lines ofthe bellows folds, substantially as described.

2. A bellows-sided bag having the triangular portions 4 folded outwardon the lines 2, x0 substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
